Do you have to buy new tires for 18‘ rims, when the stock rims are 18‘?
No, as long as the width is compatible
Look at the tires on your car. You will find a size on the sidewall. If the last number on the sidewall is 18, the tires MIGHT fit. However, some vehicles that have the same size wheels will not work with certain tires due to the width of the tire and possible rubbing on fender wells.
